DETACHABLE FIXTURE-BAR FOR WINDOW-CURTAINS.

SPECIFICATION forming part of Letters Patent No. 559, 582, dated May 5, 1896. Application filed April 28, 1894.. Serial No. 509,371. (No model.)

To all whom it may concern.-

Be it known that I, URIAH S. JAoKsoN, of Ossipee, in the county of Carroll and State of New Hampshire, have invented a new and useful Improvementin Detachable Fixture- Bars for WVindow-Ourtains, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a detachable bar to be used as a base for attaching curtain-fixtures; and it consists in combining with said bar adjustable devices for fastening it to the casing of the window, the object being to provide a bar which will form a base for attaching the ordinary curtain-fixtures and be portable and easy to attach or detach to an ordinary window-casing. This object I attain by means of the mechanism shown in the aocompanying drawings, in which- Figure l is an elevation showing a part of a window-casing, to which my detachable fixture-bar is affixed. Fig. 2 is a horizontal sec tion taken centrally through the bar, the curtain being shown in full. vertical section taken on line a; a: of Fig. 2.

In the drawings, A and A represent the two uprights of a window-casing of ordinary construction.

I3 is a bar of wood made as shown, having an openingPP at its center, and also having a longitudinal dovetail groove on its inner side, as indicated by dotted lines in Figs. 1 and 2, also shown at T T, Fig. 3. Within this groove T T, I have two sliding rods or bars 0 and C. The outer ends of these bars each has two pointed hooks D and D. The hooks D D point outwardly and are extended to engage with the inner edges of the casings A and A when the fixture-bar is applied, as shown in the drawings. If desirable, the sliding rods C C may be so far extended as to make it practical for the inturned hooks D and D to engage with the outside edges of the casingsAAQas indicated by dotted lines in Fig. 2.

Fig. 3 is a cross The inner ends of the sliding rods 0 O are turned at right angles, as shown, so as to form the parts E E, in which internal screws are cut for the reception of the screw-rod H H.

I The screw-rod H H has at one end a righthand screw and at the other end a left-hand screw, adapted to engage with the internal screws cut in the parts E E, as stated. K is a boss attached rigidly to the screw-rod H H, and is provided with holes by which it and the attached screw-rod may be turned. The fixtures L L are of ordinary construction and may be attached by nails or screws. N represents an ordinary curtain rolled up.

To fasten my bar to a window-casing I have to so adjust the sliding rods 0 C that their hooks D D come within the width between the edges of the casings A and A. Then by turning the screw E E in the right direction the hooks D D are forced into the wood of the casings A A, and the bar B is securely attached. The method of attaching the bar B by the inner hook D' D and the outer edges of the casings A A is too obvious to need eX- planation.

I claim- In detachable fixture-bars for window-curtains the combination of two rods each having double-barbed points at one end and an attached screw-nut at the other, a boss K having right and left screw-extensions which engage with the said screw-nuts, whereby the said rods are operated; with a rigid bar extending across and resting upon the windowcasings substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18thday of April, A. D. 1894.

URIAH S. JACKSON.
